What is open interest in crypto futures?

Open interest in crypto futures is the total number of contracts still open. It differs from volume and does not show price direction on its own.

Key takeaways
  • Open interest rises when positions open and falls when they close.
  • No single official total covers every exchange and contract.
  • High open interest shows more active contracts and liquidity.

Short answer

Open interest is the total number of crypto futures contracts that are still open. It counts live contracts at a point in time.

Traders watch it to gauge how many positions remain active in the futures market.

What open interest counts

Open interest is the total number of crypto futures contracts that are still open. A futures contract is an agreement tied to a crypto asset's future price. Each contract that has not been closed or settled counts once.

How open interest changes

Open interest rises when traders open new contracts and falls when contracts close. On perpetual futures, funding rates and liquidations can move the total quickly. Funding rates are payments between long and short holders.

  • Opening a new long or short position adds contracts to the total.
  • Closing a position removes those contracts from the total.
  • A liquidation closes a position by force and can lower open interest fast.

Where crypto open interest comes from

Crypto futures trade on many exchanges, and each venue reports its own open interest. Data providers add those figures together, often including perpetual futures. There is no single official number for the whole market.

Open interest vs volume and limits

Open interest and volume answer different questions. A high open interest total also has limits.

Open interest and volume compared
Open interest Volume
Counts each open contract once Counts contracts traded
Rises when new positions open and falls when positions close Counts each trade, whether it opens or closes a position
High total shows more active contracts and liquidity, but not price direction High volume shows heavy trading, not price direction

Frequently asked questions

It is neither by itself. A high total means many contracts are open, and those traders can be long, short, or both.

No. A spot trade moves coins between wallets and does not create a futures contract.

A sharp move can trigger liquidations, which close positions by force. Those closes remove contracts from the total.

No. It shows how many contracts are open, not where price is going.
